My car feels like it's not unlocking the TCC to coast at the right RPM. It feels like the brakes are working against it sometimes. I want it to release fully @ 25mph. Exactly what TCC setting in the $8D is this?

Also to that end, as I'm coming to a stop it doesn't seem like my idle goes down as fast as it should. My commanded idle RPM looks good while data logging, it just seems like sometimes the IAC isn't moving as fast as I think I would like it to for bringing down the RPM while coming to a stop. Exactly what IAC setting would this be?

Thanks in advance!

 

No one can tell me the exact TCC parameter that releases the converter to coast when braking at 25mph or less?

Also on the IAC, I think I know which parameter it is but I don't understand the ms thing. I get that the smaller the ms #, the faster the reaction, but I want to be sure I'm right. If I want it the IAC to decay faster, I take it down to like .25ms instead of higher right?

 

The converter should be released by the switch on the brake pedal assembly as soon as you hit the brakes.
